Antimony (Sb) is a hard, brittle, silverwhite metal with a relatively high specific gravity () and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification. The metal''s main use is to impart stiffness and hardness to lead alloys.
Antimony is a chemical element with the symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3).Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. Metallic antimony was also known, but it was
Although mining antimony is cheaper in China because of labour costs and the typically large deposits, the trend in declining production is set to endure. "China''s Green Shied strategy should continue to restrict antimony processing and mine supply as its government continues to clean up the environmental damage done in recent years," says Meyer.

Antimony (Sb) is a silverwhite brittle solid or a darkgray, lustrous powder. It can be harmful to the eyes and skin. Antimony can also cause problems with the lungs, heart, and stomach. Workers may be harmed from exposure to antimony and its compounds. The level of exposure depends upon the dose, duration, and work being done.
Antimony may enter the environment as a consequence of mining and processing of its ores and in the production of antimony metal, alloys, antimony oxide, and combinations with other substances.
